The domain of (a) p(x)/m(x) is (0,∞), the domain of (b) p(m(x)) is (-∞,36]∪[36,∞), and the domain of (c) m(p(x)) is [0,∞).

The domain of a function is the set of all input values for which the function is defined. Interval notation is a way of representing a set of real numbers as a range. It is written in the form of (a,b) where a and b are the lower and upper bounds of the interval, respectively.

For (a), we need to consider the domains of both p(x) and m(x). The domain of p(x) is (0,∞) because the function involves taking the square root of x, which is not defined for negative values. The domain of m(x) is (-∞,∞) because it is a polynomial and it is defined for all real values of x. Therefore, the domain of p(x)/m(x) is (0,∞).

For (b), the domain of p(m(x)) is the set of all values of x for which m(x) is in the domain of p(x). As we have already seen, the domain of p(x) is (0,∞). Therefore, the domain of p(m(x)) is the set of all real values of x for which m(x) ≥ 0. This can be represented as the interval (-∞,36]∪[36,∞).

For (c), the domain of m(p(x)) is the set of all values of x for which p(x) is in the domain of m(x). As we have already seen, the domain of m(x) is (-∞,∞). Therefore, the domain of m(p(x)) is the set of all real values of x for which p(x) ≥ 0. This can be represented as the interval [0,∞).

The domain of the function is x≥ -6. The correct option is B.

The domain of a function is the set of values that can be plugged into it. This set contains the x values in a function like f. (x). A function's range is the set of values that the function can take. This is the set of values that the function returns after we enter an x value.

Given that the function is y=√(x+6) -7. Here the domain will be all the x values we can put in the function.

When the graph is plotted for the function we get the starting point of the function as (-6,-7). So the domain will be all the values from -6 to infinity.

Step-by-step explanation:

The correct option is (d) i.e. the range of the relation is {-5, 0, 2, 4}.

What is Range ?

A function's range is a collection of all of its potential results, or alternatively, the collection of all conceivable representations of the domain's elements.

Given, {(2, -5), (1, 4), (-3, 0), (6, 2)}

Range is the result of a relation.

let say, X⇒ Y is a relation where X represents the domain and Y represents the range and both can be represented as ( X, Y).

So, all the values at the position of Y are called range of the given relation.

Hence, Range will be {-5, 0, 2, 4}.

The percent increase of the profit is 15%

In this question, the figures are given as

Profit in March = £2750

Profit in April = £3162.50

The percentage of the increase of the profit is then calculated using the following equation

Increase percentage = (Profit in April - Profit in March)/Profit in March * 100%

Substitute the known values in the above equation, so, we have the following representation

Increase percentage = (3162.50 - 2750)/2750 * 100%

Evaluate

Increase percentage = 15%

Hence, the increase in percentage is 15%

4. RSTU is a trapezoid because the opposite sides RS and UT are parallel.

5. RSTU is not an isosceles trapezoid because the diagonals are not congruent.

In order to verify that RSTU is a trapezoid, we would have to determine slope of the pair of opposite sides and check whether at least one pair of opposite sides are parallel;

RU ║ ST

Slope of side RU = Slope of side ST

Slope of RU = (y₂ - y₁)/(x₂ - x₁)

Slope of RU = (1 + 3)/(5 + 3)

Slope of RU = 4/8

Slope of RU = 0.5.

Slope of RS = (y₂ - y₁)/(x₂ - x₁)

Slope of RS = (-9 + 3)/(-4 + 3)

Slope of RS = -6/-1

Slope of RS = 6.

Slope of ST = (y₂ - y₁)/(x₂ - x₁)

Slope of ST = (-2 - 1)/(10 - 5)

Slope of ST = -3/5

Slope of ST = -0.6.

Slope of UT = (y₂ - y₁)/(x₂ - x₁)

Slope of UT = (-2 + 9)/(10 + 4)

Slope of UT = 7/14

Slope of UT = 0.5.

Therefore, RSTU is a trapezoid because the opposite sides RS and UT are parallel.

Question 5.

In order to determine whether RSTU is an isosceles trapezoid, we would have to determine length of the diagonals by using the distance formula and check whether they are congruent;

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Distance RT = √[(-2 + 3)² + (10 + 3)²]

Distance RT = √170 units.

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Distance US = √[(5 + 4)² + (1 + 9)²]

Distance US = √181 units.

Therefore, RSTU is not an isosceles trapezoid because the diagonals RT and US are not congruent.

the height of a binary tree is the number of edges in the longest path from the root to a leaf.The best-case height of a binary tree with seven nodes is 3.

A binary tree is a type of tree structure consisting of nodes that are connected by edges. The number of edges in the longest path from a binary tree's root to a leaf determines the tree's height.In the best-case scenario, the binary tree is perfectly balanced and each node has exactly two children. With seven nodes, the best-case height is three because each node has two children and three edges connect the root node to the leaves. This means that the longest path from the root to a leaf is three edges, resulting in a height of three.

Answer:

0.0806

Step-by-step explanation:

From the given information:

Number of toss = 50

The probability of having a head = 1/2 = 0.5

The Probability of 8th head occur on 12th toss can be computed as :

Pr(8th head occur on 12th toss) = Pr(7 heads in 11 toss) × P(8th head on 12th toss)

Pr(8th head occur on 12th toss) =  C(11,7) × 0.5⁷ × (1 - 0.5)⁴ * 0.5

Pr(8th head occur on 12th toss) = \(\dfrac{11!}{7!(11-7)!}\) × 0.5⁷ × (1 - 0.5)⁴ × 0.5

Pr(8th head occur on 12th toss) =  0.0806

Answer:

The probability of 8th heads,

That is occurred on 12th toss.

Step-by-step explanation:

A coin is tossed 50 times.

There are two possible outcomes of occurring a head or tail.

Probability of occurring head = no.of head/ possible outcomes

                                                    = 1/2

Total number of tossing a coin= 50 times

Probability of 8th heads occurs on 12th toss:

                                                         12C8 (1/2)8 (1/2)9 (1/2)10 (1/2)11 (1/2)12

                                 =         12C8  (1/2)8+9+10+11+12

                                                    = 12C8  (1/2)50

                                  = 12C8   / 250

                                                       = 495 / 1125899906842624

                                  = 4396.48317752 x 10-16

This is the probability of 8th heads,

That is occurred on 12th toss.

The coordinates of the reflected point P' will be (4, -3).

When a point is reflected over the x-axis, its y-coordinate changes sign.

In this case, the point P has coordinates (4,3).

To reflect it over the line x=3, we need to keep its x-coordinate the same and change its y-coordinate to its opposite.

So, the x-coordinate of the reflected point will still be 4, but the y-coordinate will become -3.

Therefore, the coordinates of the reflected point P will be (4, -3).

The total number of coins is 35

From the question, we have the following parameters that can be used in our computation:

Number of coins in the box = 7

Proportion of coins in the box = 20%

These parameters mean that

Number of coins in the box = Proportion of coins in the box * Total number of coins

Substitute the known values in the above equation, so, we have the following representation

7 = 20% * Total number of coins

Divide both sides by 18%

Total number of coins = 35

Hence, the total number of coins is 35

Answer:

See below.

Step-by-step explanation:

Call the three unknown values x, y, and z, as shown in the picture below.

According to the rule that you add two numbers to get the number below, you end up with these three equations:

x + 4 = y

x + 9 = z

y + z = 35

Now we have a system of 3 equations in 3 unknowns.

Add the first two equations:

2x + 13 = y + z

The third equation is y + z = 35, so substitute 35 for y + z in the equation above and solve for x.

2x + 13 = 35

2x = 22

x = 11

y = x + 4 = 11 + 4 = 15

z = x + 9 = 11 + 9 = 20

Number of countries would west Virginia be expected to have is  18 countries

The number of campgrounds that North Dakota has = 465 campgrounds

The number of countries = 12 countries

The number of campgrounds that West Virginia has = 711 campgrounds

Given that the North Dakota was proportional to West Virginia in the number of campgrounds to counties.

The proportion will be

465 / 12 = 711 / x

Divide the terms

38.75 = 711 / x

x = 711 / 38.75

Divide the terms

x = 18.4

x ≈ 18 countries

Hence, number of countries would west Virginia be expected to have is  18 countries

Answer:

x < -6

Step-by-step explanation:

-2x - 4 > 8

the first step is to add 4 to both sides since we need to get x alone on one side

-2x - 4 > 8

      +4  +4

so we are left with -2x > 12

we still need to get x alone so we have to divide -2 from both sides

always remember that if you divide by a negative number the inequality flips!! so instead of > it will be <.

-2x/-2 = x

12/-2 = -6

so the answer is x < -6
